At about 1:14 of the second video you have a grip on the same side sleeve and collar and you try to break her down into your guard. That will work a lot better if you escape your hips out on the same side that you have the sleeve grip, drive that arm across their body, and drive your other elbow (The collar grip) into the mat. Then you can throw your leg up high on your opponents back to help hold them down. It's my go-to for breaking someone down in closed guard and leads to all kinds of good stuff.
